IBM Research introduces consistency guidelines and the Consistency Analyzer for ALTK-Evolve in an article hosted on Hugging Face. Its GPT-4.1 evaluation on AppWorld reports a reduction in the consistency gap from 24.4 to 12.0 percentage points.

Verbatim from https://huggingface.co/blog/ibm-research/altk-evolve-consistency:

> We built a diagnostic for exactly this. The Consistency Analyzer resamples an agent's own recorded trajectory to find flip-prone decision points — steps where the model was one token-sample away from doing something different.
